Chemistry of opera

Friday, April 19th, 2013

Kate Yandell has written a thoroughly fascinating article about opera and chemistry (Atoms and Arias) for the Mar. 23, 2013 issue of The Scientist,

In a paper published earlier this year (January 14) in the Journal of Chemical Education, André [João Paulo André], who is now a professor at the University of Minho in Portugal, described his strategy for exploring the links between chemistry and opera for educational purposes.

According to André, the pairing is a natural one, as opera actually chronicled the heady, early days of chemical discovery. Joseph Haydn’s Der Apotheker (also known as Lo Speziale) and Gaetano Donizetti’s one-act opera, Il Campanello, for example, both featured pharmacists as main characters. In 1768, as Joseph Priestley, Antoine Lavoisier, and Carl Wilhelm Scheele, who would eventually discover oxygen, were immersed in their chemical labors, Haydn debuted Der Apotheker, a story about competition and love that plays out in the pharmacy. “There was something in the air. Chemistry was coming to be called a modern science,” Andé says. Il Campanello was first performed publicly in 1836, a time when many natural compounds were being isolated. It includes songs about long, complicated prescriptions. These “apothecary operas” illustrate the cultural pull chemistry used to have.

The researcher’s paper, published in the Journal of Chemical Education, has received worldwide interest. Meanwhile, Yandell’s article inspired this Mar. 24, 2013 posting on Les Vérités Scientifiques,

La constatation que nous livre l’auteur constitue-t-elle une surprise ? Non, car il en est de l’Opéra comme il en est de toute d’autre production artistique, littérature, peinture, musique : la mise en évidence d’une interpénétration entre l’actualité de  la science et l’art. Chaque époque de la société se reflète dans ce que choisissent d’exprimer ses différents acteurs ce qui permet de regarder efficacement derrière soi (cf l’exposition L’ange du bizarre. Le romantisme noir de Goya à Max Ernst au musée d’Orsay).

This is going to be a rough (very) translation and any errors are entirely mine,

The relationship between opera and chemistry should not be a surprise since opera like all the other artistic enterprises such as literature, painting, music always reflect the social and scientific interests of their own epochs as we can see in various venues, e.g. L’ange du bizarre: the dark romanticism of artists ranging from Goya to Max Ernst at the musée d’Orsay [in Paris].

As Yandell’s article notes others have observed a relationship between opera and chemistry (Links have been removed),

Jorge Calado, a retired Portuguese chemistry professor and an opera critic for the Portuguese newspaper Expresso, saw André’s talk and helped edit the Journal of Chemical Education paper. …

Calado published a book in Portuguese in 2011 whose title translates to Let There be Light! A History of Chemistry Through Everything, in which he tells the story of chemistry’s early roots through the lens of the arts and humanities, including opera.

He says that André’s paper made him want to write his own follow-up paper, and that he could think of even more examples of operas with connections to chemistry—from Jacques Offenbach’s Le Docteur Ox (1877), based on a story by science fiction writer Jules Verne, to John Adams’ Doctor Atomic (2005), which chronicles the creation of the atom bomb in Los Alamos.

Aside from the fact that it’s well worth reading, Yandell’s article is studded with opera videos that enhance the opera/chemistry relationships being described.

Here’s a link to and a citation for the research article,

Opera and Poison: A Secret and Enjoyable Approach To Teaching and Learning Chemistry by João Paulo André. J. Chem. Educ., 2013, 90 (3), pp 352–357 DOI: 10.1021/ed300445b

This article is behind a paywall.

The Feb. 14, 2013 posting on the Smithsonian blog offers a little more information about the project,

Any good opera needs a dramatic twist, and death by poison and potions fits the bill. When a team of chemists took a closer look at the formulas behind these concoctions in 20 operas, they found 25 different natural and synthetic chemical materials featured. The researchers suggest that teachers use these poison plots to engage students with chemistry, and while opera isn’t exactly an easy sell with most teenagers, learning about death by deadly nightshade probably ranks higher for most than memorizing yet another chemical formula.

The Smithsonian posting also offers a few tidbits from beyond the article’s paywall.

I believe this is a case where a few people independently had similar ideas as there is a professor in Germany who has also combined chemistry and opera although he has turned to performance. Professor Dr. Gerald Linti, at Heidelberg University has been staging musical chemistry experiments since 2004 if I’ve properly understood the German on his Special Events webpage,

  • Lange Nacht im Schloss (März 2004)

  “Chemie und Oper für Jedermann: Tannhäuser”

More recently (2009), Linti produced a Puccini night as part of his ongoing Chemistry and Opera series,

Under the title “Turandot’s Three Chemical Riddles” Gerald Linti, professor at Heidelberg University’s Institute of Inorganic Chemistry, and his students will be giving another demonstration of their legendary skill in the musical staging of chemical experiments at 6 p.m. on 26 June 2009.

He seems to have followed that up with a 2011 opera night at a conference titled, Modeling Molecular Properties, according to an Oct. 11, 2011 article by Sarah Miller for Chemistry Views,

The first day concluded with the spectacular “Chemistry and Opera” arranged by Professor Gerald Linti, University of Heidelberg. This demonstrated the beauty and fun of chemistry as Linti told the story of a Chinese Princess while his assistants performed chemistry experiments in time to live opera.

This sounds like a restaging of ‘Turandot’s Three Chemical Riddles’ from 2009. Here’s one of the images which illustrates Miller’s article,

Maybe it’s time for a new ‘chemistry’ opera. Any takers?

Citizen science = crowdsourced science?

Tuesday, November 20th, 2012

Deirdre Lockwood’s Nov. 12, 2012 article (Crowdsourcing Chemistry) for Chemical & Engineering News (C&EN) offers a good overview of the various citizen science projects and organizations while using the terms citizen science and crowdsourcing science interchangeably. For me, it’s  a ‘poodles and dogs’ situation; all poodles are dogs but not all dogs are poodles.

Here are two examples from the article,

Although the public has participated in scientific research since at least the first Audubon Christmas Bird Count of 1900, so-called citizen science has gained momentum in the past decade through funding, enthusiasm, and technology. This trend is dominated by projects in biology, but chemists are getting on board, too. NSF’s funding of citizen-science projects has grown from a handful each year in the early 2000s to at least 25 per year today.

Online gaming project Foldit has attracted many participants to find the lowest-energy configuration of proteins. Foldit players recently solved the structure of a retroviral protease that had long stumped structural biologists (Nat. Struct. Mol. Biol., DOI: 10.1038/nsmb.2119).

There’s a difference between going out and counting birds (citizen science) and 50,000 or more people solving a problem in biology (citizen science and crowdsourcing science). In the first instance, you’re gathering data for the scientist and in the second instance, you’re gathering, analyzing, and solving a science problem alongside the scientists. There is, of course, a great big grey zone but if you’re looking to participate in projects, the distinction may be useful to you. Do take a look at Lockwood’s article as she mentions some very exciting projects.

Take control of a 17th century scientific genius (Newton, Galileo, Keppler, Liebniz, or Kircher) in The New Science board game

Monday, September 17th, 2012

Thank you to David Bruggeman (Pasco Phronesis) for the Sept. 16, 2012 posting (by way of Twitter and @JeanLucPiquant) about The New Science Game currently listed on the Kickstarter crowdfunding site. From the description of The New Science board game on Kickstarter,

The New Science gives you control of one of five legendary geniuses from the scientific revolution in a race to research, successfully experiment on, and finally publish some of the critical early advances that shaped modern science.

This fun, fast, easy-to-learn worker placement game for 2-5 players is ideal for casual and serious gamers alike. The rules are easy to learn and teach, but the many layers of shifting strategy make each game a new challenge that tests your mind and gets your competitive juices flowing.

Each scientist has their own unique strengths and weaknesses. No two scientists play the same way, so each time you try someone new it provides a different and satisfying play experience. Your scientist’s mat also serves as a player aid, repeating all of the key technology information from the game board for your easy reference.

The “five legendary geniuses’ are Isaac Newton, Galileo Galilei, Johannes Kepler, Gottfried Liebniz, and Athanasius Kircher. The Kickstarter campaign to take control of the five has raised $5,058 US of the $16,000 requested and it ends on Oct. 17, 2012.

The game is listed on boardgamegeek.com with additional details such as this,

Designer: Dirk Knemeyer

Artist: Heiko Günther

Publisher: Conquistador Games

# of players: 2-5

User suggested ages: 12 and up

Description:

Players control one of the great scientists during the 17th century Scientific Revolution in Europe. Use your limited time and energy to make discoveries, test hypotheses, publish papers, correspond with other famous scientists, hire assistants into your laboratory and network with other people who can help your progress. ‘emphasis mine] Discoveries follow historical tech trees in the key sciences of the age: Astronomy, Mathematics, Physics, Biology and Chemistry. The scientist who accumulates the most prestige will be appointed the first President of the Royal Society.

The activities listed in the game description “make discoveries, test hypotheses,” etc. must sound very familiar to a contemporary scientist.

There’s also an explanatory video as seen on the Kickstarter campaign page and embedded here below,

David notes this about game quality in his Sept. 16, 2012 posting (Note: I have removed a link),

The game was heavily tested by the folks at Game Salute, and comes with the kind of quality details you might expect from games like Ticket to Ride or the various version of Catan.  If you’re interested in getting a copy of the game, it will run $49 U.S., plus shipping for destinations outside the U.S.  See the Kickstarter page for more details.

Thursday, December 8th, 2011

I found a delightful item posted by GrrlScientist this morning (Dec. 8, 2011) on the Guardian science blogs,

The holidays are stampeding down upon us. Everyone is excited and busy. But maybe you wish to take a little time to do something special with your family? Here’s a sweet little kitchen science project that you can do: grow your own snow-covered Christmas tree through the wonders of chemistry!

Here’s a video demonstrating this Christmassy home project,

You can find this video and others here on Steve Spangler’s YouTube Channel. You can also find a full set of written instructions for the ‘Magic Crystal Tree’  here on Steve Spangler’s website.

Qualitative and quantitative understanding of nanostructures by University of BC researchers

Friday, March 25th, 2011

It’s not the sexiest research (no nanobots, no self-cleaning windows, no textiles with colours never seen before on fabrics, no heating up a tumour to destroy it, etc.)  I’ve come across but developing a model that predicts a nanostructure’s optical properties is likely to prove valuable. According to the University of British Columbia Chemistry Department researchers the models could be useful with the “design of tailored nano-structures, and be of utility in a wide range of fields, including the remote sensing of atmospheric pollutants and the study of cosmic dust formation.”

From the March 24, 2011 news item on Nanowerk,

Now research published this week by UBC chemists indicates that the optical properties of more complex non-conducting nano-structures can be predicted based on an understanding of the simple nano-objects that make them up. Those optical properties in turn give researchers and engineers an understanding of the particle’s structure.

“Engineering complex nano-structures with particular infrared responses typically involves hugely complex calculations and is a bit hit and miss,” says Thomas Preston, a researcher with the UBC Department of Chemistry.

“Our solution is a relatively simple model that could help guide us in more efficiently engineering nano-materials with the properties we want, and help us understand the properties of these small particles that play an important role in so many processes.”

The findings were published this week in the Proceedings of the National Academy of Sciences (“Vibron and phonon hybridization in dielectric nanostructures”).

“For example, the properties of a more complex particle made up of a cavity and a core structure can be understood as a hybrid of the individual pieces that make it up,” says UBC Professor Ruth Signorell, an expert on the characterization of molecular nano-particles and aerosols and co-author of the study.

The experiment also tested the model against CO2 aerosols with a cubic shape, which play a role in cloud formation on Mars.

The paper, Vibron and phonon hybridization in dielectric nanostructures, is behind a Proceedings of the National Academy of Sciences paywall but an abstract is available here.

Biology is the new physics?

Monday, November 15th, 2010

Robin McKie, writing on the Guardian’s Science Desk blog (Notes & Theories), remarks on the fact that Paul Nurse, Nobel laureate for Medicine, is about be installed as president of the Royal Society at the end of November. From the Nov. 12, 2010 posting,

Paul Nurse has a modest way with his ideas. “Are you like me when you read books on relativity?” he asks. “You think you have got it and then you close the book, and you find it has all slipped away from you. And if you think you have trouble with relativity, wait till you take on quantum mechanics. It is utterly incomprehensible.” Not a bad admission for a Nobel prizewinner.

The point for Nurse is that biology is facing a similar leap into the incomprehensible as physics did at the beginning of the 20th century when the ordered world of Newtonian theory was replaced by relativity and quantum mechanics. [emphasis mine] Now a revolution awaits the study of living creatures.

There is a video of Paul Nurse talking about biology as a system on the Guardian site or you can take a look at this video (part 1 of 8 for a discussion on physics and unification theories that Nurse moderated  amongst Peter Galison, Sylvester James Gates Jr., Janna Levin and Leonard Susskind, at the 2008 World Science Festival in New York).

I find Nurse’s idea about biology facing some of the same issues as physics particularly interesting as I once found a piece written by a physicist who declared that science at the nanoscale meant that the study of biology was no longer necessary as we could amalgamate it with the study of chemistry and physics, i.e., we could return to the study of natural philosophy. About a year later I came across something written by a biologist declaring that physics and chemistry could be abolished as we could now fold them into the study of biology.

As I understand it, Nurse is not trying to abolish anything but merely pointing out that our understanding of biology may well undergo the same kind of transformation that physics did during the early part of the 20th century.
